Comparative Evaluation of Wide-Range Soft-Switching PWM Full-Bridge Modular Multilevel DC–DC Converters

Abstract: This paper discusses some wide-range soft-switching full-bridge (FB) modular multilevel dc–dc converters (MMDCs), and a comparative evaluation of these FB MMDCs is also presented. The discussed topologies have all merits belonging to conventional FB MMDCs, e.g., smaller voltage stress on the primary switches, no added primary clamping devices and modular primary structure. In addition, the primary switches in each converter can obtain zero-voltage switching (ZVS) or zero-current switching (ZCS) in a wide load … Show more

“…In addition to the research in the inverter topologies, this issue has collected important research on isolated [17,18] and non-isolated [19][20][21][22] DC-DC power converters and rectifiers [23,24]. In Reference [17], a comparative evaluation of some wide-range soft-switching full-bridge modular multilevel DC-DC converters is discussed. To realize the functions of reduced primary current loss and balanced voltage and current, a DC-DC converter with the series/parallel connection on the high-voltage/low-voltage side is presented in [18].…”
